Percona has just announced the release of Percona XtraBackup 2.2.8. Percona XtraBackup enables MySQL backups without blocking user queries, making it ideal for companies with large data sets and mission-critical applications that cannot tolerate long periods of downtime. Offered free as an open source solution, Percona XtraBackup drives down backup costs while providing unique features for MySQL backups. New Features: Percona XtraBackup has been rebased on MySQL 5.6.22. Bugs Fixed: Incremental backups would fail if the number of undo tablespaces (innodb_undo_tablespaces) was more than 1.
